Abstract: The present embodiments generally relate to a display panel and a display device which may recognize touch. A display panel is provided in which a touch sensor and a touch line are disposed in an active area in which a part of an outer edge of the touch line is curved to correspond to a curved shape of the active area in the display panel so that the touch sensing is allowed in display panels having various shapes. Further, a touch display device is provided in which an open area is located between two adjacent touch lines disposed on the display panel so that touch sensing is allowed also in the display panel including an open area such as a hole or a notch.

Abstract: Embodiments of the present disclosure are related to a touch display device (100) comprising a plurality of touch lines with a plurality of first line parts (TLa) disposed on a first sensor layer and a plurality of second line parts (TLb) disposed on a second sensor layer, at least portions of different touch lines (TL) can be disposed to overlap each other, thus a plurality of touch lines (TL) can be disposed while reducing or minimizing a reduction of an aperture ratio or a transmittance of a subpixel due to an arrangement of the touch line. Accordingly, a touch sensitivity can be enhanced by further disposing touch electrodes (TE), or the touch display device having a large area with many channels can be implemented easily by further disposing touch lines (TL).

Abstract: Provided is a touch display device. Because a shielding electrode (SE), which is disposed in a non-active area (NA) and electrically coupled between a common electrode (COM) and a common voltage supply line (CVL), is located between a touch routing line (TL) and a signal line (SL), the effects of noise caused by the signal line (SL) on the touch routing line (TL) may be reduced. Further, an encapsulation portion (ENCAP) located on the shielding electrode (SE) has a planarized structure. The resulting maintenance of a certain distance between the shielding electrode (SE) and the touch routing line (TL) may reduce noise caused by the signal line (SL) from indirectly affecting the touch routing line (TL) through the shielding electrode (SE).

Abstract: Discussed are a touch display panel, a touch display device, and a driving method thereof, wherein a constant voltage is applied to a cathode electrode during a period for sensing a finger touch or a pen touch, thereby performing touch sensing while performing display driving. In addition, a signal having the same phase and potential as the signal applied to the touch electrode is applied to the cathode electrode during a period for transmitting an uplink signal to the pen, thereby eliminating parasitic capacitance between the touch electrode and the cathode electrode, preventing transmission delay of the uplink signal, improving the recognition rate of the uplink signal, and enhancing the performance of pen-touch sensing.
